Help please. I have two 110 Atv's and replaced both batteries. One Atv works with both batteries the other Atv barely turns over because of "like" a low voltage and the charger shows full. Is there away for one to draw more power than the other? Both bikes are same yr and model.

 

A bad battery to starter connection (this includes earths to frame and engine), faulty starter, or partially seized engine will all give a lower cranking speed.

 

Swap the starters on the bikes and see if the problem goes to the other bike ?
